CUSHION-SPRING.

SPECIFICATION forming part of Letters Patent No. 792,083, dated June 13, 1905.

Application filed July 28, 1904. Serial No. 218.580-

To all whom it may concern.-

Be it known that I, WVA'rsoN R. SMITH, a citizen of the United States, residing in the city of Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in-Cushion-Springs, of which the following is a specification.

My invention relates tospring cushion work, and more particularly to means for securing the springs of such cushions to their support or stay wires.

Another object of the invention is to provide an exceedingly simple, inexpensive, durable, and eflicient means for the purpose named.

A still further object of the invention resides in the formation of a clip or other element capable of receiving oppositely-arranged stay or supporting wires and securing them firmly to springs, the clip being designed to be sprung into engagement with the wires and the springs at their points of intersection.

WVith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is a perspective view of a portion of a cushion, illustrating the manner in which a spring is supported upon longitudinal and transverse supportwires. Fig. 2 is an enlarged detail perspective View of a double-cone spring, illustrating the manner in which the stay or support wires and the spring are connected together at their points of intersection. Fig. 3 is an enlarged detail perspective View of the clip for securing the spring to the wire.

Referring now more particularly to the accompanying drawings, the reference character 1 designates transverse support or stay wires, while the reference character 2 indicates a longitudinal support or stay wire, the numeral 3 indicating a double-cone spring.

thereof when pressure is brought to bear upon the same, I arrange the transverse stay or support wires in pairs, and along the corresponding edges of the spring, and preferably, although not necessarily, at right angles thereto I dispose longitudinal stay or support wires 2, which are designed to cross the transverse wires at a point where the longitudinal wires will be placed substantially across the middle portion at the top or bottom of the springs. These wires are held in such relation as that described through the instrunnentality of detachable clips, which are preferably formed of a single piece of wire or other suitable material, each bent intermediate its ends to form an open loop or the like, 6, provided with a contracted throat, whereby the longitudinal support or stay wire 2 may be sprung into engagement therewith, the free end of the clips being formed into hooks 7 sprung over the upper or lower convolutions of the springs and the transverse stay or support wires,all of which is clearly shown in the accompanying drawings.

My peculiar arrangement possesses all the desirable features of a spring-cushion for beds, chairs, and the like, and in practice I have found that whenever pressure is applied upon the cushion the pressure is directly upon the edge of the spring, and therefore there is absolutely no tendency of the wires turning upon the springs. Another advantage derived is that when pressure is applied to any portion of the cushionit is distributed over the portion of the cushion surrounding that upon which the pressure is directly applied, and therefore the further the cushion is depressed the larger the area over which the pressure is distributed, and consequently the greater will be the resistance of the cushion. A still further advantage resides in the fact that by reason of the clips being sprung into engagement with the springs stay or support Wires the different elements are held in place even before the clips are tightened, thus rendering it much easier and more speedy to place the difierent elements in position for final adjustment. A still further advantage resides in the fact that I am enabled to employ doublecone springs in a cushion without the employment of slats for the support of the springs, which latter is a rather expensive arrangement. Moreover, when springs are mounted upon slats it is the custom to tie the springs together at their tops, which is an insecure method, and all of which I eliminate in the present construction. I gain an advantage, too, over the old method of supporting the springs upon webbing, necessitating the tying of the springs at their tops, this method being also insecure. In other words, it has been demonstrated that I can use support-wires formed in such manner as to be driven or otherwise secured in the framing of a couch, chair, bed, or vehicle seat-frame, my peculiar arrangement of the supporting-wires and their connection with the clips associated therewith serving to bind the construction together rig idly. I am also enabled to make any irregularly-shaped construction to fit any frame or seat desired. Furthermore, I am enabled to locate any particular spring forming part of my cushion.

I claim- 1. Aclip for spring-cushion work, comprising a single piece of material bent intermediate its ends to form a kink, and the free ends of the said piece of wire being directed in a plane common one to the other to form hooks, the kink being arranged in a plane at right angle to the plane of the hooks, the kink and hooks being arranged in alinement.

2. Inaspringcushion,the combination with transverse and longitudinal support or stay wires; of springs arranged with relation to said wires; and clips for securing the springs and the support or stay wires together, each clip comprising a single piece of Wire bent intermediate its ends to form a kink for the reception of a longitudinal support or stay Wire, the free ends of each piece of wire being directed in a plane common one to the other to form hooks, each hook engaging a transverse wire and the corresponding convolution of the adjacent spring, the kink being arranged in a plane at right angle to the plane of the hooks, and the kink and hooks being arranged in alinement.

3. A clip for spring-cushion work, comprising a single piece of material bent intermediate its ends to form a kink, the open end of the kink being narrower than the remaining portion thereof, and the free ends of said portions being directed in a plane common one to the other to form hooks whose open ends are narrower than the remaining portions thereof, the kink being arranged in a plane at right angles to the plane of the hooks.

4:. In a spring-cushion,the combination with transverse and longitudinal support-Wires; of springs arranged with relation to the said wires; and clips for securing the springs and the support or stay wires together, each clip comprising a single piece of wire bent intermediate its ends to form a kink for the reception of a longitudinal support or stay wire, the free ends of the wire being bent to form hooks, each book engaging a transverse wire and the corresponding convolution of the adjacent spring, the kink being arranged in a plane at right angle to the plane of the hooks and disposed between the inner side of the convolution of the springs and the transverse wire with which said convolution contacts.

In testimony whereof I affix my signature in the presence of two Witnesses.
